SPECIFICATION forming part of Letters Patent N0. 784,131, dated March 7,1905,

Application filed April 15, 1904. Serial No. 203,265.

To all whom it may concern:

Be it known that I, JACOB AssEL, a citizen of the United States, and aresident of Waterville, in the county of New Haven and State ofConnecticut, have made and invented certain new and useful Improvementsin Knobs, of which the following is a specification.

My invention relates to an improvement in knobs, the object of the samebeing to sim- I plify the construction of the same, the finished knobpresenting a neat appearance and similar in all material respects to themore expensive kinds or styles.

With these and other ends in view the invention consists in certainnovel features and method of construction hereinafter described, andpointed out in the claims.

In the accompanying-drawings, Figure 1 is a view in elevation of myimproved knob.

2 Fig. 2 is a vertical sectional view thereof. Figs. 3 and dare detachedviews, respectively, of the screw and disk. Figs. 5 and 6 are viewsillustrating the manner of assembling the screw and disk. Fig. 7 is asectional view 2 5 of the shell forming the neck or hub of the knob.Fig. 8 is a view, partly in section and partly in elevation, of the knobprior to look ing the edge of the cap-plate to the hub or neck.

3 Referring to the drawings, A represents an ordinary metal screwprovided with a head B, and C the round flat metal disk formed with acentral opening D, through which said screw is passed, the head of saidscrew being slightly larger in diameter than the opening I), asillustrated in Fig. 5, said opening being preferably square in shape,the screw-head B being round. By means of proper tools the head of thescrew is forced down into the 4 square hole I), the metal of the disk atthe same time being forced or swaged up against the screw, asillustrated in Fig. 6, thus insuring a secure fastening of the twoparts, said disk at the same time being changed in shape from flat tooval shape in cross-section.

Around the screw is fitted the shell E,formed of sheet metal, preferablybrass, and of the shape shownthat is, with an open upper end F, providedwith the shoulder G, and with a turned-in base H, provided with acentral opening I, the latter being of a proper size or diameter toallow of the passage of the screw through it, the outer edge of themetal disk C resting upon the upper edge of said hub or neck. Over thedisk C is then placed a cap K, preferably formed of the same metal asthe hub E and domed or shaped to lit over and upon the upper side orsurface of said disk, said cap being provided with a vertical rim orflange L, as illustrated in Fig. 8. ter the parts have thus beenassembled the flange L is bent inwardly, as illustrated in Fig. 2, theextreme edge of said flange fitting against the shoulder Cr of the neckor hub to impart to the linished knob a neat appearance 6 5 and concealas far as possible the raw edge of the flange. The several parts arethereby securely locked together and in such way that there is little orno liability of their becoming disengaged. 7

The knob thus constructed has all appearances of being made of solidmetal, the disk C, securely locked as it is to the screw, i1npartingsuflicient strength to the article to permit of its use for any and allpurposes for which the solid and more expensive knobs are now employed.As the several steps in its manufacture are accomplished or effected bymeans of presses it can be produced at a comparatively small cost.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A knob consisting of a screw, a disk having an opening therein inwhich is tightly 5 fitted the screw-head, a shell surrounding the upperportion of said screw, the opposite or pointed end of said screwprojecting through and beyond said shell, and a cap fitted on andconcealing said disk, substantially as de- 9 scribed.

2. A knob consisting of a screw, a disk having an opening therein inwhich is tightly fitted the screw-head, a shell forming a neck or hub onthe upper edge of which rests said disk, and with a central opening inthe base,

At 60 l swaged, a shell surrounding the upper por- I t1on of the screw,and a cap fitting over said disk and secured to said shell,substantially as described.

Signed at \Vaterville, in the county of New Haven and State ofConnecticut, this 5th day of April, A. D. 1904.

JACOB ASSEL.
